What are some examples of using core-js in my project?

Core-js is a modular standard library for JavaScript that includes polyfills for ECMAScript features. Here are a few examples of how you can use it in your project.

Can you show me how to use it for promises?

Sure! You can import the promise polyfill like this: import 'core-js/features/promise';. This will ensure that your code can use promises even in environments that don't support them natively.

What about using it for array methods?

For array methods, you can import specific features like this: import 'core-js/features/array/includes';. This allows you to use the includes method on arrays.

Are there any performance considerations I should be aware of?

Yes, while core-js is very useful, importing only the features you need can help reduce bundle size and improve performance.
